Application .my 10,1931. sensi No. 549,846 s. claims.- (ci. 36 76 Thisinventionrelates to a certain new and;

useful improvement in shoes.

My invention pertains more particularly to the manufacture of femininefoot-wear of the `socalled glued or cemented type o'f construction, inwhich more especially the prevailing mode or fashion provides a lasthaving an instep relatively very narrow in width.

VIn the manufacture of a'shoe of the character described, the usualmetallic shank-reinforcing piece or stiifener is mounted on the instepof the shoe between the pulled-edges of the upper and the outsole or,alternatively, between the upper and the insole Iof the shoe. -As atpresent constructed, however, the presence of the metal shank-stiffenerinterrupts the gluing surface at the instep of the shoe, and hence theadhesive` connection .there provided becomes insufficient for mostefficiently and .effectively securing the several parts together, thezone of weakness residing between the insole andthe upper or the upperand the'outsole according to the location `of the shank-stiffener in theshoe.

Inasmuch as it is also requisite that the shankstiffener be firmlysecured against displacement on the relatively narrow instep of theshoe, it has been heretofore customary, so far as I am aware, to tack ornail the shank-stiifener to the insole of the shoe. In practice,however, the employment of metallicjfasteners as tacks and nails givesrises to bumps and ridges in, and more especially at, the-front oftheinstep of the shoe, I due' to the comparatively light and thin-walled 3lconstruction of the shoe as manufactured 4for feminine wear, such bumpsand ridges hence lo ccurring where the flexing of the shoe-sole is inuse most pronounced, with consequent objectionably rapid destruction ofthe fabric of the stocking'of the wearer. I

My invention has hence for its chief objects the provision in ashoe-structure of a novel form.l

of insole incorporating means devoid of nails or like fastenings forretaining the shank-stiifener firmly in position and, at the same time,providing anuninterrupted gluing surface forfully adhesively securingandcorrespon'dingly strengthening the attachment of the pulled-edges ofthe upper in outsole-receptive position on the'instep parts hereinafterFigure 1;

satisfaction and. comfort ofthe user of the shoe'. And with. the aboveand other objects in view, my invention resides in novel featuresof'form, construction, arrangement, and combination vof `described andpointed out in the claims. v r

Figure 4 isa view similar to- Figure 3, showing the shank-stiffenerinserted between the insole and its pocket-forming member;

Figure 5 is a bottom plan view 'of a completed shoe manufacturedaccording to my invention; and

Figure 6 is a perspective view ofa common or standard formofshank-'stiffener suitable for use' in connection with my invention. V

Referring now more in detail and'by reference characters to the drawing,A designates the insole, which comprises abody-member 1 of suitablematerial, as relatively thin, flexible leather, composition, or thelike, fashioned'and formed suitably for its intended purpose, as wellknown to those skilled in the art.

Attached to and upon the outer face of the Yinsole-body 1 preferably bymeans o1' a suitable `90 adhesive 2, such as rubber-cement or the like,which remains viscous when in use, is a shankpocket providing member 3comprising a strap or section of preferably merely slightly pliablematerial, as cardf orber-board lor the like, which is of a length toextend from the fore-end of the :shank 4 most conveniently .alsoininsolestiifening manner' rearwardly to and over the heel-portion 5 ofthe insole-body 1. Medially in its forward margin, the member 3 100 isprovided with a. preferably V-shaped notch 6 for facilitating theendwise insertion, in presently-appearing pocket-like accommodationbetween themember 3 and the insole-body-l, 'of

a shank-stiffener B, whichl comprises a suitably elongated bar ofpreferably Ametallic-material having a suitably arch-wise conformationfor residing neatly in the instep of the finished sho'e, one form ofsuch shank-stiifenerbeing clearlyl illustrated in Figure 6.

In the manufacture of a shoe according to my invention, the insole A,constructed as described, that is to say, equipped with thepocket-providing section 3, is mounted on the customary last, and theupper C stretched thereupon and its marginal portions, as at c, snuglypulled upon and over the outer face of the insole A and its attachedsection 3 and thereto adhesively and otherwise xed and secured in thecustomary manner well known to those skilled in the art, as best seen inFigure 3. It will be observed that the presence of the member 3 permitsthe subsequent insertion and placement of the stifener B at its desiredlocation, while at the same time, the member 3 provides for a smoothflat contact of the marginal portions c of the upper C with the insole Aespecially at and with the instep of the shoe where the extremely narrowwidth of the shank necessitates the meeting engagement of the oppositeedges of the upper, in order that the gluing area may be adequate forsecuring the upper to the insole.

The upper-pulling and gluing operations being completed, as illustratedin Figure 3, and the upper C being hence now fully secured to the insoleA, the stiffener B may with the greatest ease, convenience, and facilitybe needled, so to speak, under the member 3 for location neatly andprecisely in the arch of the instep, as seen, in Figure fi.

The adhesive-body 2 by reason of its viscous nature is adapted foryielding readily in pocketproviding lmanner for accommodation of theshank-stiffener E between the insole-body l and its adheringpocket-member Il, the shankstiffener beingretainecl adhesively in itsinserted insoleaccommodated position by reason of the clinging nature otthe rubbermcement preferably e ployed :ier the purpose.

It will be understood that changes and modications in the form,construction, arrangement, and combination of the several parts of theshoe may be made and substituted for those herein shown and describedwithout departing from the nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure byLetters Patent is,-

1. In a shoe-insole, a main exible materialsection having a shoeconforming shape and contour, a pliable material section disposedflatwise upon the outer face, and having a shape and contour` to extendfrom the fore-end of the shank rearwardly to and over the heel-portion,of the main section, and an adhesive which remains Viscous when in usedisposed between said sections for securing the second section to andupon the outer face of the main section in the formation therewith of ashank stifener pocket yielding to the insertion of a shank stiffenerwhich is adhesively and permanently retained therein.

2. A shoe-insole including a main exible material-section having a shoeconforming shape and contour, a pliable material section disposed uiiatwise upon the outer face, and having a shape and contour to extendfrom the fore-end of the shank rearwardly to and over the heel-portion,of the main section, an adhesive which remains viscous when in usedisposed between said sec L tions for securing the second section toand. upon the outer face of the main section in the formation therewithof a pocket, and a shank stiiiener disposed and by said adhesive perma"nently retained in said pocket.
